Refer promptly when a girl who was developing normally (typically 6–18 months) slows, stalls, or loses skills — especially loss of purposeful hand use with repetitive hand-wringing, slowing head growth, and lost eye contact. You don't need certainty; recognise and route. Diagnosis is made only by a specialist.

*When a little girl who was developing normally begins to slip backwards, your instinct to act is exactly right — and acting early changes everything.*

## In short
Refer **promptly to a paediatrician or developmental specialist** whenever you observe a child — almost always a girl, usually between **6 and 18 months** — who was developing typically and then **slows down, stalls, or loses skills she once had**. The combination of *developmental regression* plus **loss of purposeful hand use** and **repetitive hand movements** (wringing, washing, mouthing) is the classic alarm pattern. You do not need to be certain — your job is to notice and route, not to diagnose.

## What to watch — refer when you see
- **Regression**: losing words, babble, or hand skills that were already present
- **Loss of purposeful hand use** with new repetitive hand-wringing or hand-to-mouth movements
- **Slowing head growth** (deceleration on the growth chart) in the first two years
- **Loss of social engagement or eye contact** that had previously been present
- **Unsteady, stiff, or wide-based walking**, or not walking when expected

Any one of these in a child who *was* progressing well warrants specialist referral. Two or more together — refer the same week.

## The science, briefly
[Rett Syndrome](/rett-syndrome) (WHO ICD-11 **LD90.0**) is a genetic neurodevelopmental condition, in most cases linked to the *MECP2* gene. Its hallmark is a period of normal early development followed by regression — which is why your baseline observations over the well-child visits are so valuable. Early specialist referral allows genetic confirmation and, crucially, early therapy to protect communication, movement and quality of life.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from a screening checklist or an online form. As a frontline worker, your strength is early recognition; ours is confirming the picture and building the plan. With 70+ centres across 4 states and a structured, [clinician-administered AbilityScore® assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated), we partner with you to move a child swiftly from concern to care, supporting communication and movement through [therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate).

## Trusted sources
WHO ICD-11 (LD90.0); American Academy of Pediatrics developmental surveillance guidance; CDC developmental milestones resources.

**Next step —** Don't wait for certainty. [Book a developmental assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) at your nearest Pinnacle centre, or call your district paediatric referral line the same week.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
